🔒 Encrypt / Decrypt Text

Encrypt clear text and decrypt ciphertext using AES (via Fernet).

ℹ️ About Encrypt / Decrypt Text

AES (Advanced Encryption Standard) is a symmetric encryption algorithm used by governments and security experts globally to protect sensitive information. This tool uses the Fernet implementation of AES, which provides high-level security with a 128-bit key and built-in message authentication (HMAC).

Security Best Practices:

  • Strong Passwords: We use SHA256 to derive a 32-byte key from the password you provide. Using a long, complex password increases security.
  • Symmetric Encryption: The same key used to encrypt the message is required to decrypt it. Never share your key over insecure channels.
  • Tamper Resistance: Our encryption includes an authentication tag, so the tool will fail if the ciphertext has been modified.

Use this tool for quick, secure exchange of notes or configuration secrets when you need to ensure they remain private.
